What it does
Codex can hand parts of a task to subagents: smaller assistants set up for one kind of job. This repository collects many of them, sorted into categories such as core development and quality and security.
Each subagent is a small settings file you copy into Codex's agents folder, either for all your projects or for just one.
Codex doesn't start these helpers on its own; you ask for them by name in your prompt.
Who it's for
Developers who use Codex and want specialised helpers for tasks like backend work or code review.
